I have a brand new L7 is it blown?

I have a brand new 4 ohm 15 inch L7 that i hooked up yesterday i have it running through a kicker zx1500.1 at 2 ohms. when i play it the subwoofer i hear a faint rattling noice coming from the sub. nothing is inside the box it is coming directly from the sub... is it a blown voice coil??

Check to make sure your box is securely sealed and that the box itself is not rattling. if not, most subs require a break in period where they can not be played full gain/full volume for the first 48 or so hours... did you break in your subs by paying it softly the first day and slowly turning your amps gain and receivers volume up the next couple of days. if not, it is likely blown

The CX1200.1 amp is 2 ohm stable. Hopefully, you have the 4 ohm DVC version of the Solo-Baric L7. If so, connect the DVCs in parallel (both positives together, both negatives together) to the amp. This will maximize the output power of the amp. If you have the 2 ohm DVC version of the Solo-Baric L7, the best you can do is connect the DVCs in series to the amp. This will cut the output power in half, though.

All depends on your amp. Is it 1 ohm stable or not?Parralell:positive (pos) on voice coil 1 (vc1) to Pos on vc2 and negative (neg) on vc1 to neg on vc2. Then speaker wire from amp to one vc only = 1ohm load.Series:Pos from amp to Pos on vc1. Neg of vc1 to Pos of vc2. Neg of vc2 to amp = 4 ohm load.

The L7 I have is brand new in the box (not a speaker box just the retail packaging box) and the rms is 750 watts RMS and 1500 watts peak, but you are correct they blow easy when you push rated power to them, the hifonics subs will take 1200 watts rms all day long and over 3500 peak for burping at competitions, i run mine at 2000 watts everyday in a daily driver. if you hook 1 dual 4 ohm sub to a zx1000.1 it will be 2 ohm load on the amp so you will get 1000 watts to the sub so if you want to run it slightly underpowered to keep it from blowing use the 750.1 per sub, i can do those at about 250 each shipped

the warranty starts the day you buy it for 12 months but kicker will not cover burned or blown voice coils, that is why i recommended the hifonics (which is what i use to compete with now) because they put out better quality sound and alot more of it and they will take alot of abuse, if you want boxed speakers ready to go in kicker brand ported boxes I can have them drop shipped right to your door as well, the only reason i am selling the 1 L7 i have so cheap is because a customer ordered it then never paid for it so I am selling it at cost. be careful if you are buying on ebay as you have no warranty at all and you cant force the seller to give you 1 even if they say it has 1. because authorized dealers are not allowed to do internet sales at all so kicker and most other companies will not honor the warranties.

also you dont need 2 amps you can use 1 bigger amp and still run 2 subs just by changing how you wire the subs at the amp. 1 large amp costs less than 2 smaller 1's usually just not with kicker brand

provided that the memphis studio series is still 1 ohm stable you would wire each coil of each speaker like this : posive to positive negative to negetive on the speaker using 2 jumper wires then run 1 coil from each subs positive and negative the input on the amp that amp would see a 1 ohm load from both speakers as each speaker would become a 2 ohm load. from experience, memphis does not make an amplifier that is brutal enough on power for L7 15" solos, i have the st 1600 d amp running only 2 dual 4 ohm 10 L5's and it is barely enough power for them. For less money than your 2 subs cost retail I can get you brand new matching 2000 watt true competition rated and proven 1 ohm power and 2 subs that would physically fit in your current box, i would however recommend a very very large box for 2 15" squares. you can email me at sicaudio@msn.com , my advice and system designs are always free even if you do not buy thru me. I am usually 1/3 to 1/2 what retail is with full warranties and i can drop ship anywhere in the U.S.A.

how did u wire the speaker ?what is the speaker rated at 2 ohm or 4ohm? thees kicker l7s 15 inch is rated for 1000 rms and 2000 peak the only thing that could of hapend was somthing was touching some were in the wiring or u hade the speaker wired at a load of 1 ohm

Your Kicker L7 Ohms may be too low for the MA Audio Mono block amp. The MA Audio Amp is probably 2 Ohm Stable. The kicker will either be 2 ohm or 4 ohm Dual voice coil. To eliminate the low ohms as a possible threat to causing the map to go into Protect, Wire the kicker Voice Coils in Series. This adds the ohms, so that you either have 4 or 8 ohms.

I am using the following codes to show wiring. VC1+ stands for the Kicker Subs Voice Coil #1 Postive post. AO+ is the MA audio Amp output positive.

AO+ to VC1+

VC1- to VC2+

VC2- to AO-

This shopuld give you 4 or 8 ohm depending on the 15" L7 setup. Crutchfield does not carry the Kicker L7 in 15" They do have the L5 in 15".

If you know how to read a Volt Ohm Meter, set it to OHMs 20 and measure across VC1+ to VC1- and you should see between 1.5 and 5 ohms.. Do the Same with VC2+ to VC2-. you should see the same voltage. Also read from the Voice coil metal housing to VC1+ , VC1-, VC2+, and VC2-. and you should not read any ohmage to the case. The meter should say OL, or -1.
